7 'o all w /Lom t 'may concern Be it known that we, CHARLES G. HU'rsoN and dor-1N E. YVIssLnn, both citizens of the United States, residing in the city of Richmond, in the county of W'ayne, State of In diana, have invented a new and useful Process for Producing Shaded Printing, of which the followingis a full, clear, and comprehensive specification and exposition, being such as will enable others to use the sam-e with absolute exactitude.

The object of our present invention, broadly stated is to accomplish distinct improvements in the art vof making engraved plates for printing, particularly for decora tion 4or artistic purposes in connection with advertisements, whereby an advertisement may be given distinct individuality, at the same time being simple in character, easily and quickly accomplished, attractive in ap` pear-ance, and which can bevaccomplished at a comparatively low price.

More particularly stated, our object is to provide a white on Ben Day or half tone process for 4making engraved plates and for producing shaded effects in the printing produced thereby. 1

Other special objects and particular advantages of the invention will suggest themselves in the course of the following description, and that which is new and useful will be correlated in the appended claims.

The accompanying drawings, forming a part of this specification will assist in a more thorough understanding of the invention, in which Figure 1 is a plan .view of the finished product'of our invention, as it would appear printed upon paper. Figure 2 is a fragmentary view of the lower lefthand corner of the face of the matrix when it is ready for making the engraved plate therefrom. Figure 3 is a cross section, as taken on the line 3 3 of Fig. .2. Figure 4; is a face view of a portion of the engraved plate made from said matrix, the same being ready to have printing made therefrom. Figure 5 is a cross section as taken on the line 5-5 of Fig. 4. And-Figures 6 and 7 show specimens of designs for Ben Day or shaded impressions whic are different from that shown in the other views. Figures 2, 3, a and 5 are made on an enlarged scale from that of Figure l..

In order that our invention may be more fully understood and appreciated, we will now take up a detailed description thereof, in which we will set forth the several features as fully and as comprehensively as we may.

The successful carrying out of our invention contemplates iirst the preparation of a matrix, the base of which lmay be made in y a number' of ways, but the best so far attained is built up of layers of paper pasted together forming acomparatively soft cardboard body A, shown in Fig. 2. y

A cross grain, milled, shaded, or otherwise designed surface is to be given to the body A by means of a die or metal plate on which is engraved the required design. rlhe face of the die is to be contacted with the face of the body A after which the proper pressure is applied to cause the body A to form the character, in reverse, of the face of the die plate. After the die plate has been removedthen we have the face of the body A provided with what is known as a -Benl Day surface, as denoted by B,I Figures 2 and 3.

Our invention contemplates the employment of a special ink of rather thick consistency, which is adapted to be applied with a rather soft pen or ybrush of a size preferred Vby the artist for the special work contemplated. l V

The designs, which are to show white in the final printing, should be drawn in pencil on the surface B, Iit being preferred that rather wide or heavy lines be used, probably double or spaced lines in pencil, after which said penciled lines, and the spaces between the double lines, are to be gone over or filled in with said ink by means of pen or brush, whereby the design required shows upon the Ben Day surface B on which it is superimposed.

Said ink should have the quality of expanding or rising above the surface to which it isv applied, particularly when heat is ap plied thereto, but said ink should not spread upon the surface of the paper or be absorbed thereby. The rising of the said ink causes the lines of the drawing or design to appear in cameo, as indicated by letter C in the drawings.

After the ink and the matrix have been thoroughly dried then the matrix should be placed in a casting-box and then hoty typemetal is poured directly upon and covering the surface B, and of course the lines C of the design, thereby forming the engraved plate D having the intaglio lines E which lines E are the reverse of the lines B. Certain port-ions of the plate D may be cut out for the insertion of standard type or cuts, after which 'the `plate D should be mounted when it will be ready for printing purposes.

Printing from the plate D Willproduce the finished product upon paper, as shown,Y

f the surface of said' plate -in contact with the surface of said` soft body and applying sufficient pressure whereby' the-BenDay design of the plateavill be impressed on the face of the body, thenoutlining:upon the-v Ben Day surface 'of said body the designer? letters to be; printed in f-White, then filling in said' outlines with especiallyprepared.ink

nvhich hast the character `of expanding slightly7 with heat applied thereto. After the matrixl above Vdescribed lis thoroughly dried then the next step is Vto'place the matrix ina casting box-` and pour overthe" faceof the matrix ordinary type Vmetal in melted form whereby anl exact replica of the faceof the matrix is formed in the face of the printing plate which kis formedby' type metal after it has solidified, and the said replica? forms whatmay be termed Reverse Stereotyping. The final step is printing upon paper with ther stereotype plate to accomplish the effect as shown in Fig, lof the drawing.

Iii-place of the `vertical l'inesofthe Ben Day-'surface `it is1 apparent that dotted lines 7e desire that it be understood that We are i not to bef-limited to the precise details herein set forth, but that various changes may be made 'therein Without departing from the spirit of the invention Without sacrificing any of the advantages thereof.

Having now fully fshoivn. and described ourcinvention, what We claim and desire to secure by Letters Patent, is-

l. T he herein described process which consists in preparing a matrix having `a Ben Day surface, drawing the v`desired vdesign upon the Ben Day surface With a specially prepared ink, forming a stereotype plate from the face of the matrix, and then printing fupon ypaper from the-face of the/said stereotyped plate.

2. The `herein described process which includes providing amatrix 'having ay Ben Day surface, drawing upon saidl surface a design with rather thick ink Which' has the quality of expanding when' heat is applied thereto, forminga stereotype plate on the face of ther matrix whereby the inked lines of the matrix will be yformed intaglio on the stereotyped pla-te. p f

White o n Ben Day or half tone process for making engraved plates for printing,

`which consists rof providing a Ben Day matrix, superimposing thereon material forming the ydesign to be printed in White,

(overing the face of the'matrixgwith melted type metal to provide a printing plate in` -Which said material forming the design will appear intaglio inr the printedl plate, substantially as shown and described.

In testimony whereof We* have-hereunto subscribedour names to this specification in the presence of tivo' subscribingWitnesses. v CHARLES C; HUTSON. JOHN E'VISSLER. lilitnesses Roer ith-HANDLE,
